The Ultrasonic Anemometer – a Classical Look Over

October 24th 2009 Posted to ultrasonics anemometers

As you know, anemometers are mainly used in estimating and measuring the speed of wind. With advancement in technology, many people are introducing new features to the anemometers. There are now numerous types of anemometers and that includes the ultrasonic anemometer.

First, let us run through some history. Ultrasonic anemometers were developed during the 1970s. It uses ultrasonic sound waves to measure the speed and direction of the wind.

Measuring the wind velocity is pulsed by a pair of transducers. From the pair of transducers, the measuring wind velocity combines to yield a measurement of 1-, 2-, or 3-dimensional work flow. Then, a spatial resolution is given by the path length of 10 to 20 cm of transducers.

Ultrasonic anemometers usually take measurements with very fine temporal resolution. A 20 Hertz (Hz) or better can make well for a turbulence measurement. Taking away the moving parts makes them appropriate for long term use. Automated weather stations and weather buoys are usually affected by using such cup-and-vane anemometers. It is adversely affected by salty air and some large amounts of dust.

Ultrasonic anemometers are actually handy. Aside from being a handy device, this tool can go beyond measuring wind speed. You can also get correct information regarding wind chill and the current temperature. This information may be extremely important when you are out adventuring in the great outdoor!

It has an axis, with either a moving or non-moving parts. It is great for general meteorological applications necessitating exact, reliable wind measurement. The sensor of the ultrasonic anemometer has a durable, corrosion-resistant construction. With this, it avoids any large quantities of dust to interfere with the system. Ultrasonic transducers are in opposing pairs that secure the streamline molded frame.

Most ultrasonic anemometers are fully tested. Wind-tunnel tested and calibrated, ultrasonic anemometers provide accurate wind measurement over a wide operating range.

The standard sensor actually has a lot of output options. Analog voltage outputs are being placed in for wind speed and wind direction. With this, you can now tell how much wind speed is running.

Also, there are plenty of serial output formats available on the standard sensor. These include ASCII text, RMYT and NMEA formats. Simple menus over the tool make it all easy.

All parameters are stored in a nonvolatile memory. Operating parameters can also be edited with the use of ordinary terminal software or a PC.

Environmental resistance, to avoid any accidents, is achieved with the use of UV stabilized thermoplastic, stainless steel, and anodized aluminum components. Yes, you can never go wrong with this one.

The sensor installs on a readily available 1” IPS pipe (1.34” o.d.). Some wiring connections are also made convenient and weatherproofed. Special mounting adapters, connectors, and cables are not required.

Frankly, this ultrasonic anemometer is one big daddy of all the anemometers! It can help you in times of need, especially to places who needs a meteorological station to map out winds, storms, and typhoons.

Kestrel Anemometer

August 05th 2009 Posted to Handheld Anemometers, Kestrel Anemometer

The Kestrel Anemometer has different models and functionalities built-in. However, there are specific features and “weather measurements” technologies that make the anemometer of Kestrel head and shoulder above that of other brands.

Using the Kestrel’s sensitive impeller technology, you are able to get exact and precise wind speed information. Sometimes, these accuracies may be a matter of life and death in precarious weather conditions.

In addition, the Kestrel anemometer has an external temperature sensor. This allows you to measure the temperature of water and snow, not to mention, open air. It also has waterproof casing which keeps the equipment safe from water. Moreover, the casing makes the handheld anemometer float so that you will not lose your meter in a flood situation. It also comes with a hard slide-on case, lanyard, and battery.

The Kestrel anemometer also features wind speeds display in: Beaufort Wind Scale; Knots; MPH; KPH; or Feet Per Minute which allows the scientist in us to interpret the information as we wishes.

And, here are some specs for the blue blooded engineers in us to drool over:

Features:
* Ultralight impeller is mounted in jewel bearings for precision, wide range of speeds and low startup speed
* Impeller is shock-mounted in a glass-reinforced plastic housing
* Waterproof and floats
* Quick-response, external thermometer
* Innovative design for stability and accuracy in abrupt condition changes
* All instruments and accessories are completely assembled in the USA
* Actual size: 4.8″ x 1.7″ x 0.6 ” (size w/out case)* Protective cover with sure-grip molding
* Data hold function
* Large easy-to-read display
* Patented, user-replaceable impeller (no tools needed)

The Kestrel Anemometer accurately measures:
* Current Wind Speed
* Average Wind Speed
* Maximum Wind Speed
* Wind Chill
* Air, Water, and Snow Temperature
* Displayed in Fahrenheit or Celsius w/ accuracy of +/-1°

What You Must Know About Anemometers

July 16th 2008 Posted to Handheld Anemometers, davis wind anemometers, ultrasonics anemometers, why use anemometers

If you have a child in school, you may get some questions like why use an anemometer? What is a permanent mount hot wire anemometers, or what is a wind study wireless anemometer?

Basically, an anemometer is an instrument that is designed to measure wind speed. With the advancement of technology, this instrument has advanced into various types like hot wire, davis wind, ultrasonics, aluminium cup, wireless anemometers, and more.

One of the brand names in the market is Lacrosse. There are also Ahlborn anemometer, propeller anemometer and boat anemometer spares available.

The most portable are the handheld anemometers and they make it easy and affordable for the amateur weather watcher to track and predict wind speed as well as wind chill and temperatures.

Most handheld anemometer can do the following:
· Display current, maximum, average wind speeds
· Measure wind speed in mph, Km/h, m/s, or Knots
· Report wind chill and temperature in Fahrenheit or Celsius

It is a small device, measuring only 4 inches by 2 inches. It is however highly accurate and also displays the current temperature. The wind speed is measured in rages from 0.4 mph to 67 mph so it’s suitable for just about every climate this side of Antarctica.

It has a Beaufort wind scale bar graph display which makes it easy to read. The temperature is checked every 10 seconds meaning that you won’t miss a beat. Wind chill is also measured, resulting in a truly accurate account of the current weather conditions.

It also features a very clear LCD backlight and comes in a water resistant case, as you would expect for a weather device!

It is an awesome product to carry around as it is so small it can fit in your pocket. There is also a neck band for easy carrying and the thorough instruction manual clearly explains how to operate the handheld anemometer.

The LaCrosse model runs on just one lithium cell battery which should last for a year, so it is an extremely durable and affordable product to own. It also comes with a one year warranty.

Owning a handheld anemometer is a rewarding experience as you can truly track the weather in your backyard on a daily basis. From this you can predict trends and even forecast the weather for the following day or week! That is certainly something to impress your friends and family with. And if all else fails, try a windmill with anemometer for a weather study trip!
